` tion being to provide a switchwhich can be ,controlled from a point remote froirnas well asadjiacent to the switch proper, the said invention coinprcliending both direct incchanical operation and remote operation through the inediuin of electromagnetic ap'- pai'atiis. i

It' further has for its obiect to provide a switch controlled by an electromagnetic de vice by which it can be thrown to 'either on `or ofi' position at one point', andcan be thrown to one of said positiins but not to theother from another point.

The following. is a descriptioirof the ap- )aratus embodying iny invention, reference ing had to the accompanying drawings, in which# Figure 1 is a side elevation, partly in sec tion, and showing circuits in diagram. Fig.

2 is a View of certain details of construction. 1 VVrepresents the base of a rotary switch. 2 represents a rotatable controlling spindle, by which the switch proper actuated. l

l3 represents the switch blade which, to gether with the usual terminals 3I may be contained in a. suit able box-like receptacle 4.

Externally located is a 'inanually'operable handle 5 suitably secured to the spindle or inain operating nie'rnber 2 whereby the blade may be turned to throw the switch on or oil' at will, by hand.

6. is a gear or pinion mounted on the rear of the spindle,l and provided with ratchet -nected from said switch when said switch is4 mechanism arranged so as to be clutched therewith when rotated in one direction,-

and to be 'free thereof when rotated in the .opposite direction,^being operatively disconactuated' by the handle, so thatltlie handle is movable independently thereof'. 'and being operatively connected to t'lie. ,fswitch only when -energized, its operati ve' connection being thus intermittent.4 y v 7 is a rack suitably guided and having teeth* ineshing with said gear 6 andre- Specication of Letters Patent. i Appiicatibn inea Aprn 5,1907. seriaiNo. 366,606.

' tracted by a spring 7*. 8 is a core of a solenoid, 9 i'cpreseiiting one solenoid winding Aconnected to any convenient source of current. In the form shown, the solenoid circuit 9 is a shunt from the main line circuit wires l0-l1, between the switch and the inain source of current.

12-13 represent terminals of the main line, leading to the contacts 8a for the switch blades 3.

14 is a circuit closer in the solenoid cir- 'cuit 9. The ends of the solenoid circuit 9 are suitably connected at all times with the inain circuit, so that by closing the circuit closer 14, which may be located at any desired point ren'iote frointhe switch proper, the solenoid is energized, thus causing the racl; 7 to move in a direction to actuate the` pinion 6 in a direction to rotate spindle 2 and operate the switch proper. The result is that while the switch may be-operated directly by the handle shown, it niay also be operated indirectly through the medium of the solenoid brought intov play by closing ,the circuitat anyv remoteA point. In order that the Switch may be thrown oil' from ,a

point at which it cannot also be thrown on, I provide a second winding 15 for the solenoid in shunt tothe mainconductors 10-11 on thev translating device side of the main switch. IThis winding is controlled by any one of the several circuit closers 16. Vheii the circuit is closed4 at `16,'the switch, it

already7 on, `will be thrown oit. If the switch is in theotf position the closing of the shunt at 16 will have no effect, since the y nevertheless be revolved electromagneti cally, the handle being unscrewed by the moveinent.` This 'inakes it. impossible for any one to .actuate the switches 16 and hold the handle so as to prevent the circuit controlled thereby from being opened, since that circuit is controlled by the main electromagnetically actuated switch as well as by the switches 16,-and will be broken by that switch whenever either of the switches 16 is actuated, even if the handle' 5 is held from turning. The electro-magnetic means trolled by the switches 1G is free from .conwf trol by the 'actuatiiig'handle If itwere not 5 for this freedom from control by the manual operating means, the-main switch might be manually restrained from moving when i `the switches 16 were actuated to close their circuit, resulting in the overheating and possible burning out'of the coil 15. The switch is therefore guarded against accidents which ight result from careless manipulation by ignorant or mischievous persons, v vApparatus embodyingmy invention will 1 5 'be found useful wherever it is desirable to employ an apparatus wherein one can, at

, any time, open or close theimain'line circuit while at the main line switch, or at some point remote. from the main line switch, or where it is desired to have full control at one point and partial control at the other points.v l -The solenoid, or other magnetic control,
